Ah, thanks for pointing that out to me. I haven't even looked in the Overture forum yet- in fact all I've done is download the HPL and OALWrapper Source so far. But I'll download everything else a little later today probably and then maybe I can get it compiling properly (though I can easily imagine other problems potentially coming up.

As for Ryonez, I'm not particularly familiar with Java so I don't know how similar it is to C++ (though from what I've seen I think the syntax is pretty similar). That said though, if you don't know that much C++, trying to take a look at something the size of HPL/Overture mightn't be the best idea, depending on what you're hoping to get out of it. But if you had any particular questions related to the source code or the project overall you could still ask them.
